There is no constant ratio for image size to object size
It depends on,
1. Image size
2. Sensor specifications (ex: Focal length of the camera)
3. Camera to Object distance
4. Acquisition angle (Theta)
5. Light focusing
6. Need some Known object values for determine unknown object size etc...
Well, It could be magnification.
principle of microscopy includes 2 important aspects: 1. resolution and resolving power- the resolving power of a microscope is defined as the minimum distance by which 2 points must be separated in order for them to be perceived as 2 separate points rather than a fused image. 2. magnification- Linear (sometimes called lateral or transverse) magnification refers to the ratio of image length to object length measured in planes that are perpendicular to the optical axis. A negative value of linear magnification denotes an inverted image. Longitudinal magnification denotes the factor by which an image increases in size, as measured along the optical axis.
There are many different microscopes currently on the market. Most of these microscopes come with different levels of magnification so that you can view an object in different ways. It is important to make sure the microscope you choose to use will have the correct maginfication you need.

Density is the ratio of mass to volume. Thus, the density of an object is the mass of the object divided by its volume.
It's a ratio of Image distance to the Object distance.
refractive index is something that measures the speed of light as it goes through an object is the ratio between real depth(the distance from the object to the surface of the medium) and apparent depth(the distance from the virtual image pf the object to the surface of the medium) dazani ch? siri bxo zurnay leda!

It's called the "scale."
compression ratio=uncompressed image size/compressed size
Aspect Ratio If an aspect ratio of an image is changed the image will be distorted either vertically or horizontally
You could pair this word up with just about anything else except for "camera" (e.g. macro lens/shot/flash/capable/work/setting/photo etc.) To the best of my knowledge, there is no such thing as a "macro camera". If you're trying to determine what macro images are, this definition hails from the old days of film: it is an image where the ratio of the recorded image size to the actual object size is from 1:1 to 10:1. In other words, the image recorded on film is the same size as the object (1:1) or is up to 10x larger than the object. If you go beyond 10:1 you have branched into photomicrography. Anything less than 1:1 is "close up" photography.

The name for the ratio of a diagram measurement to actual measurements is the scale.
The ratio for a diagram measurement to the actual measurement is known as the key.
